What kinds of network file systems are you sharing from you NAS, SMB/CIFS, Apple Share, NFS, etc.? I assume that the Belkin is the only DHCP server? I assume we are talking about TCP/IP here not some other protocol?

My first guess is that you should be fine, but depending on how you have things configured it might be an issue.

Huh? Currently I just mount the other machine on the one I need to transfer files. Are you asking how I'll format the NAS?

Actually both the Wireless G & Airport are set for DHCP. Is that wrong?

What I'm wanting to do is:

Separate the "B" & "G" wireless
Printing is done wirelessly via the Airport Express and it's there for the "B" network for the slower machines.
I got the Wireless G for the 4port router more than anything but, once I got it I thought I would separate the wireless to keep the speeds running at max.

I have not used their products recently, but Buffalo's Linkstation designs have been fairly powerful and well reviewed. I personally own an Iomega NAS, and it will work with any OS and multiple machines simultaneously.
